Guide 02
how to write a startup tagline.
A tagline is the line under your name. Its job is to tell a stranger what you are, who it's for, and what they get, before they decide whether to read on.

What a tagline has to do
Most visitors read the name and the tagline, and little else. The tagline has to pass the test our launch checklist sets: one sentence, jargon-free, and specific to your customer.
It doesn't need to be clever. It needs to be clear enough that someone can repeat it to a friend.
A simple formula
[what it is] for [who] that [outcome]
- What it is:the category, in plain words. “Bookkeeping” beats “financial operations.”
- Who:a specific person or team. “Freelance designers” tells a reader whether they are the audience. “Businesses” does not.
- Outcome: what changes for that person. Describe the result, not the feature list.
You don't have to use the exact words. The three parts are the point.
Length
The submit form accepts taglines from 10 to 140 characters. Anything outside that range is rejected (validation in src/server/actions/startup.ts).
Separately, our launch checklist marks 10–110 characters as the sweet spot. That figure is a guideline the checklist uses to rate your tagline, not a limit the form enforces. Aim for under 110 and keep the 140 ceiling in mind.
Before and after
The “before” lines could describe almost any company. The “after” lines name a person and a result.

Common mistakes
- Jargon.Words like “synergy,” “leverage,” and “composable” hide what the product does. Use the word your customer would use.
- Vague superlatives.“Best,” “revolutionary,” and “all your needs” are claims nobody can check, so readers skip them.
- Naming competitors.“The Notion alternative for X” ties your page to someone else's brand and leaves the reader to work out what you do.
- Features instead of outcomes. A list of capabilities says what you built. The outcome says why someone should care.
- Exclamation points and keyword stuffing. Both read as noise.
Checklist
- Can a stranger say what it is after one read?
- Does it name who it's for?
- Does it state an outcome rather than a feature list?
- Is it 10–140 characters, and ideally under 110?
- Is every word one your customer would actually use?
- Is there no competitor name and no superlative?
- Does it match the hero copy on your page when you read them side by side?
